UPCO has redesigned its sinker bar product line and invested in new computer controlled equipment to provide you with the best value in the market.
Our sinker bars are manufactured from straightened, hot rolled steel. After machining the pin blanks, sucker rod threads are cold formed, thread protectors are applied and the bars are coated and bundled.
UPCO Sinker Bars have an elevator neck at one end and two wrench flats at each end. An optional fishing neck can be added. Our standard configuration has sucker rod threads, but polished rod threads are available.
